So I used nou's script here for the first 3. https://gitea.nouspiro.space/nou/astro-soft-build Which works perfectly. What did you use for PHD2? Kind regards Steve

Are you presenting?

Hi Andy, Great job, but help me here. What did you do? This what I think you did, please tell me if I'm wrong: 1 - Bought two RAA Muon Detector kits here: https://www.ukraa.com/store/categories/cosmic-rays/muon-detector-kit. 2 - And two enclosures here: https://www.ukraa.com/store/categories/cosmic-rays/muon-detector-enclosure. 3 - Assembled them both; 4 - Tested them with the Beta particles from a naturally occuring K40 source (bananas); Is that right? How do you then test for actual cosmic ray muons, and how do you distinguish between Muons and Beta particles? Total cost was about £328? Kind regards, Steve.

Flat rotation curve and dark matter aren't really the same thing. You got a flat rotation curve - amazing, but there are other explanations to the flat rotation curve such as MOND (Modified Newtonian Gravity/ Milgromian Gravity) or Quantised Inertia. Honestly none of these theories are really very intuitive. For instance, it seems very counter-intuitive to me at least, that the amount of dark matter that you need is an exact straight line from an apparantly random point midway out from the centre of the galaxy.

I can't find my fake just now, but they look realistic too. It's just the printing on the outside that's a bit different.

Yes, I think what's what mine is too, although you have to watch out for fakes!!

This one.

Link or image? Maybe it's the one I got, I don't recall, we've just moved and it's all in boxes still.

Fantastic. How much did it cost?

Hi Andy, It's a great start, but I think it's upside down. Here's a site arguing which way up it should be: http://galaxymap.org/drupal/node/171 (NB EVen NASA got it the wrong way round ). Steve.

I'm pretty sure. What are the dimensions of the individual elements? I think the rules are, resolution is set by the largest dimension (ie the array), the sensitivity is set by the elements. If I'm wrong, Im suresomeone will correct me. Steve.

I'm using them as a stepping stone into spectroscopy. I've joined a group of six or eight like minded folks to try to track a group after rapidly varying Be stars for longer periods of time than we might otherwise do. I'm using a lowspec 3 and just putting the final touches to a star'ex. Kind regards, Steve.

No, it's even better. But it was @skybadger

Fantastic. This is the biz. Tx.

Hi Folks, Does anyone have a list of Be stars? Especially ones currently earlier in the night. Eg in Lyra. Kind regards Steve.
